Coal Dust Explosion and Suppression Modelling

Without adequate controls in place, dust in underground coal mines can be an explosion hazard. This video shows a Computational Fluid Dynamics (CFD) simulation of a methane-initiated coal dust explosion and water suppression in Kloppersbos 200m tunnel in South Africa. Simulation was performed using Openfoam CFD software and specially developed algorithms on a 128 processor machine. Coal dust is colored by temperature. Water is shown in liquid phase only.

Simulations of alternative scenarios of stone dust and coal dust loadings, as well as initial methane explosion strength, are possible.

This is "moving camera" view with the open-end of the 200m tunnel being clear at the end of the video.
